I believe it's an old ferrite core inductor (possibly from a magnito or old radio).

Electro magnet or transformer. Maybe from a telephone, magneto, etc.

Your item is an Steel Laminate Core fixed value Inductor...or inductance coil. It can't be a transformer because it only has one wire on each end of the coil...with no center tap. A transformer would have to have (three or four wires). Likely used in an audio circuit.

This would be the same thing minus the "wax paper wrap".... https://www.parts-express.com/Data/Default/Images/Catalog/Original/266-574_HR_0.jpg

Maybe a doorbell transformer or something from Crocker-Wheeler, an old fan company

All of the above are good answers, but I'm hoping it was from an old quack medicine shock therapy contraption... which really isn't very likely, it's just a fun application for these.

I was wondering why my electric shift on my 2000 450 Honda ATV 4x4 was "touchy".... Do you live near Middle TN.

No idea here.
